SPECIFICATION forming part of Letters Patent No. 533,621, dated February5, 1895. Application iiled April 18, 1892. Renewed Tune 7, 1894. SerialNo. 513,752. (No model.)

To all whom t may concern.-

Be it known that I, CHARLES ALBERT THOMPSON, a citizen of the UnitedStates, residing in the city of Washington, in the Distrct of Columbia,have invented a new and useful Improvement in Hand Stamps, of which thefollowing is a specification.

My invention relates to improvements in hand stamps by which the oneblock can have one or several rubber stamps secured to it and each bebrought into position as required; also to aframe for holding the blockby which clear and perfect copies can be made. l attain these objects bythe mechanism illustrated in the accompanying drawings, in which- Figurel, is a side elevation; Fig. 2, a front View; Fig. 3, a detail part; andFig. 4, the block, showing the rubber plates, with the end pieces usedin turning it.

B is a block of Wood as ordinarily used to secure the rubber plate toand on each end there is a wire m m which serves as an axle for theblock B. These Wires passloosely through the parts 'n n of a frame bbinto metal pieces H H. By means of a set screw the piece H on one end istightened to the wire fm.. The piece H on the opposite side is held onthe Wire fm. by riveting the end of the wire or in any convenient way,but left free to turn. The metal pieces H. H. are made similar to theshape shown in Figs. 3 and 4-one having a notch w on the lower corner.The frame t h' is made of metal and is simply for the purpose of holdingthe block B. It is made of a shape like that shown in Figs. l and 2--thepart h bent atright angles, Fig. 2., and the part b Working on an axleat E.

The side castings A.are of metal and shaped on the front edges as shown,Fig. 1. being a true curve with the center at E. On one of thesecastings A. is a small projection or lug a used for the purpose oftripping or upsetting the block B in its passage up and down. At adistance above the lug a and on both castings A. are two pieces C tosupport the inking roller Gr.

D. CZ. is a lever to 'force the frame b h down if pressure be necessary.This lever D is journaled in the castings A as shown in both 5o Figs. land 2.

e is a spring secured at one end to the bed plate F. and the otherworking loosely under the frame b b. The object of this is to hold theblock B up in the position shown in Fig. l.

The curve of the sides of the metal pieces H, is the same as the curveon the front edges of the castings A.

The operation of my machine is as follows: If desired to print the wordThompson the set screws: is loosened and the block B turned so the wordis down and against the bed plate F. When the frame Z2 b is in theposition shown in Fig. 2, the screw :c is tightened against the Wire m.lVhen the lever D is drawn forward, Fig. l-the spring e will force theframe b h' up and as the metal piece H comes in contact with the lug athe block B is turned as shown by the dotted lines and as the block Bpasses the inking roller G. the type face T is inked. When the lever D.is pushed back the frame b b' is forced down and the type face againinked. The block B turns when the piece H strikes the lug o, and animpression is made on any paper already on the bed plate F. The notch wis to allow the piece H to turn withoutbeing thrown oft the edge of thecasting A.

VVhatI claim as new, and desire to secure by Letters Patent, is

In a hand stamp, the combination of a base .with an oscillating frame bb pivoted thereon, a stamp block revolubly mounted in the frame, a pieceH., a guide, a tripping lug a, and an inking device, substantially asand for the purpose set forth.

CHARLES ALBERT THOMPSON.
